PHP Requires Chilkat v11.0.0+

Use a Custom Set of Trusted Root Certificates

See more Certificates Examples

Demonstrates how to build a set of trusted root certificates to be used globally by all Chilkat classes. Chilkat2 PHP

<?php

use Chilkat2\Cert;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Thawte is a certificate authority that provides a .zip download of their
// root CA certificates:  https://www.thawte.com/roots/index.html
// The direct download link is: https://www.verisign.com/support/thawte-roots.zip
// Note: The above URLs are valid at the time of writing this example (29-May-2015).

// Assuming the .zip has already been downloaded, open it and load each .pem file into
// our trusted roots object.
$zip = new Zip();

// Open a .zip containing PEM files, among other things..
